I have a 10- 12 month old Dominique hen, not sure exactly what she weighs, but her weight has not seemed to change much since she was healthy, which was only a couple days ago. I got home from work today and noticed she was not in the run, which is unusual. When I opened my coop, she was laying on her side with her legs sprawled to one side. She had defecated in the same area multiple times and was laying in it. Her feces was also very runny and watery, I know this because I saw her defecate once while tending to her. I removed her and cleaned her off. I then tried to stand her up, and she wobbled back and forth some and then either tried to walk or just fell over, loosing all balance. I have 3 other hens of the same age and breed which are all fine in appearance and behavior. I looked her over thoroughly and can not find any injuries or abnormalities at all. I feed them a mIxture of crumbles and scratch with oyster shell and insoluble crushed granite mixed in. The coop is 4 x 8 x 6 and the run is 8 x 10 with cedar chips in the coop and chips and wheat straw in the run. I have removed her and have her in a kennel with bedding and water as well as oatmeal and chopped hard boiled egg, but she will not drink or eat on her own. I live in Raleigh NC and it has been unseasonably hot lately (in the 80s) and a buddy suggested it could be dehydration, but I don't have a clue. I have scheduled a vet appointment for her tomorrow afternoon, but would like to help her until then or on my own if possible, due to money beig tight. All of the ag stores around me have closed already, so I only have access to the grocery. I care for my chickens as much as I do my dogs and other animals, and am very worried about her, as well as the fact that she is my best laying hen. Any help or advice would be much appreciated and valued as a new member to the forum. Thank you in advance!
